Had no issues and then suddenly any video file that I bring in won't show up but instead I get a grey box with a red and green arrow. If I double click I get a box to find the file again but even if I point to the file again it dosn't show up. If I try to drag and drop on the timeline i get a message that it can't find the file even though the file exists and will open in Windows, Quicktime, etc.

Well, when I use Get Media the box where I used to see the start of the video I get a grey box with the red and green semi circular arrows. I've trying bringing in a few different video files (mpg, mp4, avi), all located on my internal hard drive. I even tried a mp3.

Yes, Get Media worked fine and then suddenly later the same day it wouldn't work anymore. I don't recall if any other software was installed or more likley updated at that time. This happend about 3 weeks ago and I just got back to it. First thing i did was reinstall Pre and also Quicktime and K-Lite. No luck with any of that though.

Hm-m, was K-Lite added between when it worked, and when it quit working?

The reason that I ask is that some of its components have been known to cause issues with some Adobe programs. One component, FFDShow, has killed display of Clips in Adobe Premiere Pro. However, others here seem to have no issues with it, and PrE.

For that "gray box," have you updated your video driver to the latest version from nVidia, or ATI/AMD? If not, I would do that immediately, and test. Do not trust Windows to tell you, if you have the latest driver. Compare the installed driver version/date, with the latest one for your video card/chip, and OS, on the mfgr's. Web site.

I have 86gb free but havn't defragmented or run Advanced System Care on this computer yet. K-Lite was previously on the computer when Pre was working.

I'll check again for the nVidia GeForce 310M driver. There is a much newer driver on nVidia's site that I did try to install yesterday but got the message that it wasn't compatible. I'll check again to make sure I have the latest verson from Dell.

The hard drive is on auto defrag. Video driver has a slgihtly higher number than on the Dell site for my model which is a bit strange. Is there any way to force an install the latest from nVidia or is this a bad idea?

When I bring in a video file, like I said, it dosn't show the video but it's a grey box with the arrows in it. If I double click on that box it asks me to find the file again. If i click on the file again, I get the following message "This type of file is not supported, or the required codec is not installed". Dosn't mater what kind of video or audio file it is. Those files do work in other video or audio programs on the computer.
